Yuav ua li cas yog Tsev Cog Khoom Npog zaj duab xis ?
Greenhouse covering film, also known as agricultural plastic, polyethylene, poly film or greenhouse plastic, is a durable and inexpensive way to cover your little backyard hobby greenhouse or large commercial greenhouse project, it is also widely used in single and double layer greenhouse.
Optimized teeb Faib:
Diffused light reaches plants from many different angles while regular light transmission remains
zoo li qub, optimizing teeb tis rau tag nrho cov qhov chaw hauv lub tsev cog khoom
Light from the sun passing through the covering film and entering a greenhouse is split into direct and diffused. Light diffusion causes a film to look hazy to human eye – this doesn’t mean, however, that the film is less transparent. The PAR (photosynthetic active radiation) received by plants is the same
Tiv thaiv cov nroj tsuag los ntawm sunburn:
Light diffusion reduces shadows, ensures more uniform distribution of light in the greenhouse so that it reaches even the lower parts of the plants, prevents burnings and offers a moderate cooling effect.
Nyuam qhuav pib sau, dua qoob loo Loo:
It is now generally accepted that diffused light has a positive effect on plant growth, especially for spring and summer crops and in areas with strong sunlight.
The diffusion film is very popular all over the world, which is used widely in France, Spain, Israel, Turkey, Australia, African countries etc., because the diffusion film with uniform distribution of light is good for the plant’s phot-osynthesis.
It is proved by experiments that, regardless of planting cucumber, tomato, or flowers, the diffusion film can in-crease the yield of them
The increased yield percentage is as follows: Cucumber(4-10%),Tomato(8-10%),Mixed Sweet Pep-per(5%),Rose(5%). This increased yield is caused by the lights of Diffusion film, the Diffusion lights are going to all parts of plant, making the photosynthesis more sufficient.
UV tiv thaiv, zoo Durability thiab thiav:
Advanced UV stabilizers maximize physical properties for the longer life of film and help protect it from chemical damage. Apart from the occasional tornado, hurricane, or hailstorm, more damage is done to greenhouse film by sunlight than any force of nature. It’s the ultraviolet component of sunlight that does the damage, resulting in yellowing and weakening of the covering film. Fortunately, you can buy greenhouse film that has built-in resistance to the damaging effects of UV radiation. If you buy a plastic that does not have UV protection, you can expect a very short service life from that poly – very possibly no more than a single year. Most greenhouse films that ARE treated with UV protection, on the other hand, have a service life rating of from 3 to 5 years.
Anti-Txia & Anti-Plua plav
Droplets formed at the inside surface of greenhouse films due to water-condensation have negative consequences on plant quality and growth, as they reduce light transmission and increase the incidence of certain diseases, To prevent this from occurring, we use a special anti-drip (AD) additive, which flattens the water droplets into a layer of water that runs down the sides of the greenhouse. So the film with the function of Anti-Drip can reduce the need for pesticides, delay the onset of diseases, significantly improve light transmission, promote early harvesting, and contribute to enhanced yield quantity and quality.
Los ntawm kev siv peb advanced multi-khaubncaws sab nraud povtseg extrusion technology, peb ntxiv ib plua plav-txo additive rau lub sab saum toj txheej ntawm peb cover films. Nyob rau hauv no, lub sab qaum txheej ntawm lub hau zaj duab xis yog tshwj xeeb tshaj yog tus thiab qhov no ho thiaj li tsub zuj zuj ntawm hmoov av.
Muaj zog hno thiab tsim kua muag Kuj
An unique manufacturing process conditions and quality control procedures provide to the films excellent mechanical strength, we are using special high-strength polymers. Our advanced Japanese resin technology provide TOYOTANI’s films with superior tear strength, These films offer additional safety in critical areas with very strong winds.
100% mas Hom Tshiab ntaub ntawv
Fenglong has 20 years experience and careful selection of raw materials, we import the additives from Japan, and other materials from USA, Japan, Iran, Saudi Arabia, to keep the film top quality.
Zoo Thermic nyhuv
TOYOTANI® special Multi-layer films, containing a combination of EVA and Infra-Red additives skillfully structured in the middle layers, which absorb the Infra-Red radiation and reduce heat losses throughout the night.
Hwm Hydrotalcite khoom Yuav Khaws Zoo Thermicity
Qhov zoo ntawm cov thermic films yog:
- Kev pab tiv thaiv los ntawm te thiab tsawg kub.
- Smoother kub nco thiab ntau dua hmo ntuj kub zuag qhia tag nrho.
- Txo zog noj rau cua sov.
- Ntau dua cov qoob loo tawm los.
- Nyuam qhuav pib sau.
- Zoo zoo ntawm cov qoob loo.
Yuav ua li cas thermal Tsev Cog Khoom films ua hauj lwm?
Thaum lub sij hawm lub hnub nyob rau hauv ib tug tsev cog khoom, lub hnub ci, muaj ob pom lub teeb thiab luv luv yoj infrared lub teeb, yog absorbed los ntawm cov nroj tsuag, cov av thiab cov ntaub ntawv ntawm kev tsim kho uas tau nyob rau hauv lawv cua sov li. Thaum lub sij hawm hmo ntuj tag nrho cov khoom uas tau absorbed no lub zog yuav tso nws li ntev yoj infrared tawg. Ib tug thermal zaj duab xis yuav nqus thiab re-ntaiv no lub zog, kev tswj ib tug ntau dua tsev cog khoom kub thiab yog li ntawd ib tug qis cua kub nqi. Thermal films feem ntau them rau lawv tus kheej thaum lub sij hawm thawj xyoo ntawm kev pab them nqi
Kev cai txiav Length thiab dav
Special cut lengths and width are available, so you can order the exact amount at different size according to your different greenhouse disign.
Tsev Cog Khoom Npog zaj duab xis yog muaj nyob rau hauv ib tug ntau ntawm thickness, feem ntau xws li ntawm 3 mils (0.08mm) mus txog 8 mils (0.20mm), Ceeb toom: 1 mil yog 0.0254mm.The thickness ntawm lub poly zaj duab xis feem ntau raug nyiaj lub durability thiab xav pom useable lub neej ntawm cov yas. Tsis tas li ntawd, lub thicker ntawm yas, tsawg lub teeb yog kis tau los ntawm nws. Tab sis lub thickness ntawm cov yas muaj me ntsis cov nyhuv raws li tus nqi ntawm cov tshav kub uas yuav poob los ntawm cov yas.
6 thiab 8 mil (0.15mm thiab 0.20mm) films yog cov feem ntau siv thickness ntawm tsev cog khoom yas.
